Part 1 Flashcards
What is the recommended rate of compression for an adult?
At least 100 per minute.
❝A rate of 120 per minute is considered optimum.❞
Does the heart restarts after someone performs CPR?.
No.
❝CPR will not restart the heart but may delay tissue damage associated with inadequate oxygen supplies❞
When calling EMS, What information should you tell them?
- What happened and the condition of the injured person.
- The location of the emergency and a call-back number.
- How many persons are involved?
- Your name and the first aid provided.
Regardless of who calls, the person relaying information to EMS should state: their name, number of patients, exact location, call-back phone number, condition of the patient(s), what happened and a description of the care provided. The caller should not hang up until the operator releases them to return to the patient.
What is the recommended depth of chest compression for an adult?
At least 2”
❝The depth of the compression should be at least 2 inches (5 cm). One-third of the chest depth is considered optimum. It is important to release the pressure on the chest between the compressions but without losing contact between the chest and your hands❞
The goal of CPR (without defibrillation) is to maintain the adequate circulation of oxygenated blood to vital organs like the ______________ and ______________.
The goal of CPR (without defibrillation) is to maintain the adequate circulation of oxygenated blood to vital organs like the Heart and Brain.
❝The goal of CPR is not to restart the heart but to provide critical blood flow to the heart and brain and keep oxygenated blood circulating. CPR delays damage to vital organs (such as the brain) and improves the chances of successful defibrillation.❞
Is placing an unconscious, breathing victim in the recovery position important to maintain an open airway, and help minimize the potential for blood and vomit to cause an obstruction?
Yes.
❝If normal breathing is present or resumes, place the unresponsive, injured person in the recovery position to ensure an open airway. This helps to prevent blood and vomit from obstructing the airway or flowing into the lungs. Should vomiting occur or when blood or other fluids are present in the mouth, gravity will aid in removal and minimize the chance of aspiration.❞
Why is it important when removing gloves after providing first aid, to keep the outer surface of the glove from touching your skin during removal?
The gloves protect a rescuer but may be contaminated while providing aid. Be careful to avoid skin contact with bodily fluids when removing gloves.
What is the compression/ventilation ratio for an adult?
30:2
❝After each cycle of 30 compressions, provide two rescue breaths. Each rescue breath should take about one second. Watch the chest rise and return to its normal position before giving the second ventilation.❞
Inhaled air contains ______________ percent oxygen. Exhaled air contains about ______________ percent oxygen. The use of supplemental ______________ can greatly increase the amount delivered to tissues.
Inhaled air contains 21 percent oxygen. Exhaled air contains about 16 percent oxygen. The use of supplemental oxygen can greatly increase the amount delivered to tissues.
❝The exhaled air used during rescue breathing contains about 16 percent oxygen compared with 21 percent in room air. Despite this reduction in oxygen concentration, rescue breaths still provide adequate oxygen supplies to sustain vital organs. The use of supplemental oxygen can greatly increase the amount of oxygen delivered to tissues❞
During CPR, ______________ ______________ take over the temporary function of the heart, while ______________ ______________ deliver air to the lungs.
During CPR, Chest compressions take over the temporary function of chest heart, while Rescue breaths deliver air to the lungs.
❝Chest compressions temporarily take over the function of the heart, manually circulating blood in the body. Rescue breaths deliver air to the lungs and ensure a supply of oxygen to the body, especially critical areas like the heart and brain.❞
Are any breath sounds at all considered normal?
No.
❝Abnormal respirations are commonly associated with cardiac arrest. Breathing efforts may be infrequent, irregular, diminished or characterized as noisy gasps known as agonal breathing. This type of breathing is quite different from that seen in a normal resting or sleeping person and is not adequate to support life❞
should a person with back or neck injuries be placed in the recovery position?
No.
❝People with suspected spinal injury should not be placed in the recovery position as it places them at increased risk of further injury❞
